a small monkey oftenly mistaken for a little person or a human in general.there is only one left in the world. the ONYX looks like a stud. although of its hairy feartures most humans cant tell with just the naked eye. Usually when scientists try to uncovert he mysteries of the ONYX, they get hairy balls thrown at them.
